Hardware MAC address change using live CD?

rated 0 times [ 3] [ 0] / answers: 1 / hits: 1672 / 1 Year ago, tue, may 30, 2023, 1:56:01

I would like to save a new MAC to the hardware, so I can use the new MAC address on Windows. I am using live CD of the newest Ubuntu. If I try ifconfig it doesn't save it for my Windows system. I don't have admin permissions on Windows.

I need to change MAC address so the Windows one changes too.

What network card? Some NICs store the MAC in EEPROM that can be reprogrammed by software. If your card is setup like this, and the Linux driver exposes an interface to the EEPROM, ethtool (available in Ubuntu repos) can read/write to it.

This article looks like a good overview of the process of rewriting the MAC. Don't blindly use the examples from there though, since they may not be suited for your card.
